Jasper N. Jacobs was born in 1836, Ohio, the son of John H. (b. 1803) and Ann (b. 1802).
New York or Vermont native John married Connecticut- or Virginia-born Ann and by 1832 had settled in Ohio where they lived for some years. Sometime after 1843 John moved his family west and eventually settled in Michigan. By 1850 John had settled the family on a farm in Algoma, Kent County where he worked as a carpenter, and where Jasper lived with his siblings and parents.
Jasper was married to Philena Perry on September 15, 1856, in Kent County, Michigan.
By 1860 Ann was living with the family of Samuel Duffey in Plainfield,, Kent County.
Jasper was 25 years old and residing in Solon, Kent County when he enlisted in Company F on May 13, 1861. He was sick in the hospital in July of 1862, but eventually recovered and returned to the Regiment.
Jasper was a Corporal when he was killed in action on August 29, 1862, at Second Bull Run. He was presumably buried among the unknown soldiers whose remains were removed from Second Bull Run to Arlington National Cemetery.
No pension seems to be available.
In 1870 John, who had apparently remarried to New York native Rebecca (b. 1830), was still living on a farm in Algoma, Kent County. (Interestingly, just two doors away lived the “Peary” family, James, age 57 and Sarah, age 38.)
